Description

電動送風機１２は電源コード２に接続される。電動送風機１２は、動作した際にごみを吸引する吸引風を発生させる。本体制御部１３はそれぞれスイッチ１４，１５を切り替えて電動送風機１２と電動機１０の動作を制御する。スイッチ１４，１５は例えばサイリスタであり、本体制御部１３からスイッチ１４，１５をＯＮする点弧位相角を指示する点弧位相角信号を受信し、電動送風機１２と電動機１０に入力される電力を制御する。電源回路１６は電源コード２に接続され、電源プラグ３がコンセントに接続された際にＡＣ電源（商用電源）を直流低圧電源に変換して本体制御部１３に−５Ｖの電力、定電流回路１７に−１２Ｖの電力をそれぞれ供給する。 The electric blower 12 is connected to the power cord 2. The electric blower 12 generates suction air that sucks dust when operated. The main body control unit 13 controls the operations of the electric blower 12 and the electric motor 10 by switching the switches 14 and 15, respectively. The switches 14 and 15 are thyristors, for example. The switches 14 and 15 receive a firing phase angle signal indicating the firing phase angle for turning on the switches 14 and 15 from the main body control unit 13, and the electric power input to the electric blower 12 and the electric motor 10 is received. Control. The power circuit 16 is connected to the power cord 2, and when the power plug 3 is connected to an outlet, the AC power (commercial power) is converted into a DC low voltage power and the main body control unit 13 is supplied with -5V power and constant current circuit 17. -12V is supplied to each .

図５は、スイッチ部の出力に応じて電動送風機を制御する場合のタイミングチャートである。本体部１は周期的にデータを送信する。本体部１がデータを送信している際、本体部１の本体制御部１３はデータの読み取りを行わない。手元操作部６は本体部１からのデータを受信してからデータを送信する。手元操作部６がデータを送信している際、手元制御部２２はデータの読み取りを行わない。これにより、データの衝突が抑制され、通信配線９上の信号が双方のデータの論理積となることはない。このため、送信した信号とは異なった信号となることを防止できる。また、通信信号が読み取れない波形となることを防止できる。 FIG. 5 is a timing chart for controlling the electric blower according to the output of the switch unit. The main body 1 periodically transmits data. When the main body unit 1 is transmitting data, the main body control unit 13 of the main body unit 1 does not read the data. Operation portion 6 transmits the La Defense over data or receives data from the main unit 1. When the hand operation unit 6 is transmitting data, the hand control unit 22 does not read the data. Thereby, the collision of data is suppressed, and the signal on the communication wiring 9 does not become a logical product of both data. For this reason, it can prevent becoming a signal different from the transmitted signal. It is also possible to prevent the communication signal from becoming a waveform that cannot be read.
